A 1-1/4-inch NPT to 1-inch NPT reducer connects threaded components of those nominal pipe sizes, but the fitting’s gender and style must match your setup. For a male-to-female reducer bushing, the DAN SPEED and TAISHER options match the specified sizes; TAISHER is listed as a two-piece set. Horiznext is another single-piece male-to-female option. Beduan is a female-to-female coupling-style alternative. The Metaland fitting is included as a size-check example, but it is not a 1-1/4-inch-to-1-inch reducer.
| Product | Thread configuration | Best suited for |
|---|---|---|
| DAN SPEED | 1-1/4-inch male × 1-inch female | Buyers who need a stated pressure limit |
| TAISHER | 1-1/4-inch male × 1-inch female | Buyers wanting two bushings |
| Horiznext | 1-1/4-inch male × 1-inch female | Buyers seeking a single 304 stainless fitting |
| Beduan | 1-1/4-inch female × 1-inch female | Connections requiring female threads at both ends |
DAN SPEED 304 Stainless Reducer Bushing
This reducer bushing has a 1-1/4-inch male NPT end and a 1-inch female NPT end. Its listed material is 304 stainless steel, and the product specifies a maximum working pressure of 150 psi at 70°F. It is best for buyers who need the male-to-female configuration and want a stated pressure limit to compare with their application.
The listing notes that NPT tapered threads are intended to create tighter seals than straight threads. Confirm that both mating components use compatible NPT threads, and use a suitable sealing method for the application. The stated pressure limit applies at 70°F; do not assume it remains the same at other temperatures.
TAISHER Two-Piece Hex Bushing Set
TAISHER lists two 304 stainless steel hex reducer bushings, each sized 1-1/4-inch NPT male by 1-inch NPT female. The listed operating temperature range is -65°F to 250°F. This set is best for buyers who need more than one matching reducer or want a spare for a compatible plumbing or industrial connection.
The hex shape provides wrench flats for installation. The product description does not state a working pressure, so verify pressure suitability with the seller or manufacturer before using it in a pressurized system. Choose this set when the two-piece quantity is useful; a single-fitting option may be more appropriate otherwise.
Horiznext 304 Stainless Reducing Bushing
Horiznext describes this as a single 1-1/4-inch MIP by 1-inch FIP reducing bushing made from 304 stainless steel. MIP and FIP refer to male and female pipe threads; the listing identifies the thread standard as NPT. It is best for buyers seeking one fitting with the same male-to-female size conversion as the DAN SPEED and TAISHER options.
The product description emphasizes installation with NPT threaded fittings and pipes but does not provide a pressure rating or temperature range. Avoid relying on it for a particular pressure or temperature duty without confirming those specifications for your system.
Beduan Female-To-Female Reducer Coupling
Beduan’s fitting is a 1-1/4-inch by 1-inch female-thread reducer coupling, rather than a male-to-female bushing. The listed material is 304 stainless steel, and its stated operating temperature range is -65°F to 250°F. It is best for a setup where both connected parts have male NPT threads and the reducer must provide female threads at both ends.
Choose this only if a female-to-female coupling matches your connection layout. Its thread orientation differs from the three male-to-female bushings above, and the listing does not provide a working pressure rating.
Check This Metaland Fitting’s Size Before Buying
This listing is not a match for a 1-1/4-inch-to-1-inch reducer: it specifies a 1-inch male NPT end and a 1/4-inch female NPT end. It is made from 304 stainless steel, but those material details do not change its stated thread sizes. Do not choose it for the requested reduction. It is included here to help prevent a size mismatch when comparing similar reducer-bushing listings.
Buying Guide
Which thread configuration do you need?
Check whether each existing pipe or fitting has male or female threads. A male-to-female reducer bushing, such as the DAN SPEED, TAISHER, and Horiznext options, fits a different connection layout from Beduan’s female-to-female coupling. Matching nominal sizes alone is not enough if the thread genders do not fit.
What do 1-1/4-inch and 1-inch mean?
These are nominal pipe thread sizes, not measurements of the fitting’s outside length. Compare the NPT size markings and connection type rather than treating the numbers as exact outside-diameter measurements. The Horiznext listing specifically notes that the size codes identify NPT threads, not fitting length.
Does the fitting’s material or rating suit the application?
Several listed options are 304 stainless steel, described as corrosion resistant. That does not establish suitability for every fluid, environment, or pressure. The DAN SPEED listing gives a maximum working pressure of 150 psi at 70°F; the other matching options do not provide a pressure rating in the supplied descriptions. Check the operating requirements before installation.
How many fittings should you buy?
The TAISHER option is listed as a two-piece set. DAN SPEED and Horiznext are described as single fittings, while Beduan is a coupling-style alternative. Select by quantity and connection style, not by the word “reducer” alone.
Frequently Asked Questions
Is a 1-1/4-inch NPT to 1-inch NPT reducer the same as a bushing?
Not always. A bushing is commonly a male-to-female fitting, while a reducer coupling can have female threads at both ends. Check the product’s thread genders.
Can I use the Metaland fitting for this size conversion?
No. Its listed sizes are 1-inch male NPT to 1/4-inch female NPT, not 1-1/4-inch to 1-inch.
Which listed product states a pressure limit?
The DAN SPEED listing states a maximum working pressure of 150 psi at 70°F. The supplied descriptions for the other products do not state a pressure rating.
Are all these fittings 304 stainless steel?
The supplied descriptions identify the DAN SPEED, TAISHER, Horiznext, Beduan, and Metaland fittings as 304 stainless steel. Verify the exact product specifications if material grade is critical.
